Participants will learn about SHRP2 Project R06G, which identified nondestructive testing technologies for evaluating the condition of various tunnel linings and tunnel lining finishes. The project advanced both hardware and software development for the most promising technologies and demonstrated the technologies' ability to detect flaws within or verify the condition of the targeted tunnel components.

The Webinar will highlight the work of SHRP2 Project R03, which documented worker fatigue impacts during rapid renewal operations in the highway construction industry. A new Fatigue Risk Management Guide for Rapid Renewal Highway Construction Projects is now available, as well as the project report, Identifying and Reducing Worker, Inspector, and Manager Fatigue in Rapid Renewal Environments. Participants will learn how to define the risk factors associated with workplace fatigue, identify procedures to manage those risk factors, and apply the new guide's recommendations for use in their own agencies.

The session will summarize SHRP2 Project R19B, which developed new design codes, performance measures, and implementation tools that can lead to longer and more predictable bridge service life. The project produced a report, Bridges for Service Life Beyond 100 Years: Service Limit State Design, which addresses the performance measures and design procedures that maximize the actual life of a bridge. Webinar topics will also include proposed changes to the American Association of State Highway and Transportation Officials (AASHTO) Load and Resistance Factor Design Bridge Design Specifications.

The Webinar will highlight the use of 3D engineered models in transportation construction work. This session is fifth in an FHWA series on 3D Engineered Models for Construction.
